one who listens to any subgenre of techno or electronica music. can sometimes be a derogatory term, thus, it carries stereotypes.

the following is a conversation that actually happened to me.
guy: dude, what the hell are you listening to?
me: well, that depends on what you want me to say. If i say, "electronic music" then you won't care. but if i use the word "techno" then you'll call me an idiot. so whichever one you want to hear is fine by me because i don't care what anyone else thinks.
guy: you listen to techno!? you're such an idiot!
